[Intel-gfx] [PATCH 09/11] drm/i915/uc: prefer intel_gt over i915 in GuC/HuC paths
Chris Wilson
chris at chris-wilson.co.uk
Sat Jul 13 10:00:14 UTC 2019
From: Daniele Ceraolo Spurio <daniele.ceraolospurio at intel.com>
With our HW interface logic moving from i915 to gt and with GuC and HuC
being part of the gt HW, it makes sense to use the intel_gt structure
instead of i915 as our reference object in GuC/HuC paths.
